The final and most public phase of a complex Medicaid fraud case at WellCare Health Plans Inc. began in March with the criminal indictment of five top executives, including Thaddeus M.S. Bereday, the company’s former general counsel.

The scandal came to light in October 2007, when the FBI and Florida state investigators raided WellCare’s Tampa offices. In 2009, the company agreed to pay $80 million to avoid criminal prosecution. It also pledged to work with investigators in the criminal case against the executives, including the former CEO and CFO.
